Definitions
- the invention relates to a method for the production of oxygen according to the Preamble of claim 1.
- the invention is based on the object, such a method energetically cheaper.
- the first pressure, on which the first and the second partial flow of the air in common be compacted, is slightly above the operating pressure of the pressure column.
- the Pressure difference is preferably such that the first partial flow of the air Flow resistance between the air compressor and the pressure column without can overcome pressure-changing measures, and is for example 0.1 to 0.5 bar.
- the operating pressures at the top of the rectification columns are for example 2.5 to 10 bar, preferably 4 to 7 bar in the pressure column and 1.05 to 4 bar, preferably 1.1 to 1.5 bar in the low pressure column.
- an air compressor is the only one external used driven machine. This brings the total air to the first pressure, at the same time the inlet pressure of expansion machine and cold compressor represents.
- the oxygen product can under a discharge pressure be obtained, for example, 0.5 to 4 bar, preferably 1 to 3 bar over the operating pressure of the low pressure column, without that an additional Energy consumption compared to the recovery of the oxygen product Low pressure column pressure is connected.
- the cold-compressed partial air flow is in the indirect heat exchange with the evaporating oxygen at least partially, preferably completely or in the essentially completely condensed.
- the condensate is then released and fed to the pressure column and / or the low pressure column.
- the process of the invention is particularly for the production of impure Oxygen with a purity of 80 to 99.5 mol%, preferably 90 to 95 mol% suitable under superatmospheric pressure.
- the process stream, the work performing relaxation is subjected, however, by a third partial flow of the first pressure formed compressed compressed air.
- the indirect heat exchange in which the Product oxygen vaporizes against the condensing second partial stream of air, in the main heat exchanger.
- the Separate secondary condenser provided as the main heat exchanger Circulation evaporator is formed;
- a Countercurrent heat exchanger or a falling film evaporator as secondary condenser use.
- the Brake device can, for example, by a brake fan and / or a Brake generator can be formed and located outside the coldbox, the to Insulation of the cold parts of the apparatus is used. This can give energy to the Given environment and thus won the necessary for the process cold be without an additional relaxation machine is used.
- relaxation machine, cold compressor and braking device immediately mechanically coupled, for example via a common shaft.
- the invention also relates to a device according to claim 5.
- Atmospheric air 1 is after flowing through a filter 2 in an air compressor 3 compressed to a first pressure, which is approximately equal to the operating pressure of the pressure column 13 is. (To overcome the line losses, the first pressure must be slightly above the Pressure column pressure are, for example, less than 1 bar, preferably 0.5 bar or less.)
- After removal of the compression heat in the aftercooler 4 flows compressed air to the first pressure 5 to a cleaning device 6, by a A pair of reversible molecular electroluminescent adsorbents is formed.
- the first Pressure compressed air flows after cleaning 6 via line 7 to Main heat exchanger 8 and is cooled there in part to about dew point.
- the cold air 9 is at 10 in a first partial flow 11 and a second partial flow 12th divided up.
- the first partial flow 11 is directly into the pressure column 13 of the Rectifier fed directly above the sump.
- the Rectification system also has a low-pressure column 14, which has a common condenser-evaporator, the main capacitor 15 in Heat exchange relationship with the pressure column 13 is.
- the second partial flow 12 is in a cold compressor 16 to a second, higher Pressure, via line 17 to a secondary capacitor 18, as Circulation evaporator is madebiildet (not shown), guided, and there essential completely liquefied.
- the liquefied air 19 is via a valve 20 in the pressure column 13 throttled, either at the bottom (see drawing) or at an intermediate point, some theoretical or practical soils above the feed of the first partial flow 11 is located.
- Another proportion of the first pressure compressed and then purified Air 7 is at an intermediate temperature from the main heat exchanger. 8 led out and forms the third partial flow 21.
- This is in a Relaxation turbine 22 work-performing relaxed to about low-pressure column pressure and passed via line 23 directly to the low pressure column 14.
- the relaxation turbine 22 is over a common shaft with the cold compressor 16 and not one coupled brake generator coupled.
- Liquid raw oxygen 24 from the bottom of the pressure column 13 and liquid nitrogen 25 from the main condenser 15 are cooled in the subcooling countercurrent 26 and abandoned via the valves 27 and 28 to the low-pressure column 14.
- nitrogen-rich residual gas 29 is withdrawn and after heating in the subcooling countercurrent 26 and in the main heat exchanger. 8 discharged via line 30. It can also be used as a regeneration gas in the Cleaning device 6 are used (not shown).
- liquid oxygen falls with the required purity.
- a part is withdrawn via line 31 liquid, by means a pump 32 brought to the required discharge pressure and under this pressure evaporated in the secondary condenser 18.
- the gaseous pressure oxygen product flows via line 33 to the main heat exchanger and is via line 34 below about Ambient temperature delivered.
